ABSTRACT:
A videoconferencing system includes a videoconferencing arrangement with the capability to automatically determine whether a videoconferencing or conventional telephone call is being initiated. In one embodiment, a portable telephone unit includes a preprogrammed memory storing codes that indicate whether a telephone number input to the telephone unit should be used to initiate a videoconferencing or conventional telephone call. If a conventional telephone call is being initiated, the video processing functions of the videoconferencing unit are not activated and the user proceeds with the conventional telephone call. If a videoconferencing call is being initiated, the videoconferencing unit establishes a data connection with a compatible device at the remote end of the communications channel and proceeds with the videoconference. In another embodiment, a portable telephone unit interfaces with a remotely located switch circuit and the switch circuit determines whether the telephone call input to the portable telephone unit should be used to initiate a videoconferencing call or a conventional telephone call. The switch circuit includes a preprogrammed memory storing codes that indicate whether the telephone number input to the telephone unit should be used to initiate a videoconferencing or conventional telephone call.
